FEED-BOARD FOR TH RASHING-MACIHINES.

SPECIFICATION forming part of Letters Patent No. 457,948, dated August 18, 1891.

Application tiled February 18, 1891.

To all whom i?? may concern.

Be it known that L-JOHN HENRY BARR, a citizen of the United States, and a resident of Meriden, in the county of Jeerson and State of Kansas, have invented certain new and useful Improvements in Feed-Boards for Thrashing-Machines; and I do hereby declare that the following' is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference bein g' had to the accompanying drawings, which form a part of this specieation.

My invention relates to improvements in feed-boards for thrashing-machines, the obj ectA being to provide an adj ustable board for the above purpose, the angle of which, with reference to the cylinder of the machine, can be regulated at will for the purpose of varying the size of feed-opening' to suit different varieties of grain.

The invention consists in the novel construction and combination of parts, hereinafter fully described, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a portion of a thrashing-machine with my improved feedboard applied thereto. Fig. 2 is a plan view of the board detached. y

In the said drawings, the reference-numeral l designates the frame of the machine, and 2 is the beating-cylinder, which may be of any ordinary or suitable construction.

The numeral 3 denotes the side bars of the machine, which projectA outwardly, as shown in 1, and to which is secured one of the leaves of the adjustable feed-board. The feed- Serial No. 381,912. (No model.)

board consists of two parts or leaves 4 and 5, one of which 4 is secured to the side bars 3, as above set forth. The two leaves are hinged together by means ofthe hinges 6, the leaf 5 being adj ustable with relation to leaf 4, so that its angle or inclination may be varied. The lower edge of the leaf 5 rests just in front of the beating-cylinder, so that the grain from theboard can be readily fed thereto. Secured to the under side of leaf 5 is a forwardly-proj eeting lever 7, which is adapted to engage with a segment 8, having a series of ratchetteeth, by means of which the leaf 5 can be adjusted and held in position.

The operation of theinvention will be readily understood by those skilled in the art to which it pertains, and its advantages and merits will also be apparent, so that no detailed description is necessary.

Having thus described my invention, what I claim is- The combination,with a thrashing-machine, of an adjustable feed-board made in two parts 4 and 5, the part 4 being rigidly secured to the side bars of the machine and provided with a downwardly projecting segment having' rack-teeth and the part 5 hinged to part 4 and provided with a rearwardly-extending lever adapted to engage with said segment,whereby the size of the feed-opening may b e varied, substantially as described.

In testimony thatv I claim the foregoing' as my own I have hereunto afxed my signature in presence of two witnesses.

J OI-IN HENRY BARR.
